Occupational Safety and Health: Basic Approach & Policy

At the Haseko Group, we establish a Group-wide Basic Policy for Safety and Health Management that stipulates a safety and health policy for Group employees each year, execute thoroughgoing initiatives to eliminate occupational accidents and work to create safe and comfortable workplaces on an ongoing basis.
Furthermore, construction sites of Haseko Corporation establish a safety and health policy and specific implementation measures including partner companies under the Safety and Health Management Plan each year. In order to minimize occupational accidents, not to mention reducing fatal and serious accidents/disasters to zero, we treat the elimination of factors that cause human errors as a priority issue in our activities.

Framework for Promoting Health and Safety

Although the Haseko Group has not been accredited with Occupational Health and Safety Management Systems ISO 45001 (formerly OHSAS 18001), it has voluntarily set up the Safety and Health Central Committee as a supervisory system in which directors oversee safety matters, chaired by the President and Representative Director of Haseko Corporation to administer the respective Safety and Health Committees. Monthly reports on trends in the number of accidents at construction sites are submitted to the Board of Directors of Haseko Corporation, and in the event of a serious accident, prompt reports on the causes and preventive measures against recurrence are provided, thereby establishing a system of director oversight of safety. In addition, at the Safety and Health Committee of each Group company, the committee and occupational physicians work together on an ongoing basis toward creating safe and comfortable workplaces.
In FY2025, with “Eliminate the occurrence of human error and aim for zero accidents and zero disasters” as our slogan, we executed thoroughgoing initiatives to eliminate occupational accidents at each business site, and committee members for safety and health promotion of each company continuously played a central role in creating a safe and comfortable workplace environment.
For elimination of occupational accidents, we conducted activities by setting the frequency rate of occupational accidents at 0.60 or less and the severity rate of occupational accidents at 0.01 or less as target figures for accidents^* at construction sites. For the creation of a safe and comfortable workplace environment, we further promoted non-working days together with workers in order to rectify long hours of work as part of Workstyle Reform at construction sites. We also made Group-wide efforts in this area at the organization level in collaboration with MOSt Activities.
At meetings of the “Safety and Health Central Committee,” the President and Representative Director of Haseko Corporation, who chairs the committee, and the committee members, comprising the officers in charge of each department and the presidents of each Group company, as well as the representatives of the labor union of the Haseko Group, participate in deliberations and discussions regarding safety and health. The Safety and Health Committees of Group companies are composed of members of whom half have either been nominated by the labor union of the Haseko Group or represent a majority of the employees.

Activities to raise safety awareness

To eliminate occupational accidents, it is essential that each employee remain aware of safety and act accordingly in their daily work.
In addition to proactively using posters and bulletin boards to raise awareness, we conduct regular risk assessments through regular safety patrols at construction sites where Haseko Group projects are underway, thereby strengthening our safety management practices.
With regard to safety and health education for our own employees, Haseko Corporation provides mandatory annual training as part of practical, year-based and position-based programs for young to mid-level employees in the construction divisions. These programs cover fundamental matters such as safety- and health-related laws and regulations, key management points for each type of construction work, and accident case studies. In FY2025, a total of 1,260 employees participated in these training programs.
In addition, we provide safety and health education for cooperating companies that engage in construction work with us as partners. This includes training for foremen and personnel responsible for safety and health.
Furthermore, as part of hands-on training for cooperating companies, we introduced “Experiential Safety VR Training” using virtual reality (VR) equipment in December 2021. By allowing participants to simulate occupational accidents in realistic VR environments, we aim to further enhance safety awareness.

Ensuring safety on construction sites

Before beginning work on new construction projects, Haseko Corporation holds meetings of the Construction Plan Examination Committee aimed at ensuring appropriate and smooth construction. In addition to the Construction Dept. and site foreman responsible for managing the construction site, the Safety Management Dept., the Technical Support Dept., and the Environmental Systems Dept. also participate in committee meetings. They examine the various risks associated with each project and provide guidance and advice to the Construction Dept. and site foreman. Likewise, in terms of safety management, we evaluate risk based on the unique circumstances of each project and implement suitable countermeasures to ensure safe construction work.
After construction work commences, we conduct Worksite Safety and Health Patrols, where employees in the Safety Management Dept. visit all construction sites. Employees carrying out these patrols inspect the status of each site’s safety and health management, the completeness of relevant documentation, etc. based on a checklist, and provide necessary guidance on improvements. The results of these inspections are shared with the Construction Dept. responsible for managing the construction site and the officer in charge of the construction divisions. The Internal Auditing Department also audits each form of management implemented by the Safety Management Dept. through its internal audits.
The scope of audits by the Internal Auditing Dept. is not limited to construction sites and includes the status of management related to industrial safety and health, such as audits of the status of working hours management across all divisions, including Group companies.

Heatstroke countermeasures on construction sites

Haseko Corporation makes human life the highest priority on its construction sites, and from this perspective of ensuring safety, we position measures to handle health risks in hot environments as an important issue and continuously strengthen our heatstroke countermeasures.
The risk of heatstroke associated with outdoor work has increased with rising summer temperatures over recent years, and this has the potential to cause serious industrial accidents in absence of suitable countermeasures. Based on this awareness, we have established the Rules for Countering Heatstroke that also comply with amendments to laws and regulations, and enact thorough management of working times and break frequency in response to the WBGT heat index. Along with this, we have enhanced daily health management on construction sites through measures including increasing the frequency of physical condition checks and employing checklists in order to gain a reliable understanding of the health status of each individual worker while handling workers with existing illnesses, elderly workers, and other such workers prone to the effects of heat on an individual basis together with cooperating companies, and by taking these actions we are working to prevent heatstroke and mitigate the risk of severe illness. Furthermore, we have implemented multi-faceted measures that include the use of technology including heatstroke prevention watches and helmet-mounted devices, the installation of sunshade equipment on the uppermost part of building frames, and a “drink 1.5 liters of water a day” campaign to encourage proper hydration.
Through these initiatives, we aim to create workplaces that do not permit severe industrial accidents caused by heatstroke.

Status of occupational accidents and initiatives aimed at preventing recurrence

In FY2025 (April 2025 to March 2026), there were 7 industrial accidents resulting in one or more days of lost work time (a total of 173 days) on construction sites where Haseko was the main contractor. In terms of the type of accident, the most common was falls (three), followed by getting caught in equipment (two), and then cuts and abrasions (one) and collisions (one). While the number of accidents was half that of the previous year, the fact that the severity of each accident increased due to the occurrence of accidents involving piledrivers and other heavy machinery presented issues that need to be addressed.
When an occupational accident occurs, the Construction Department and the Safety Management Department in the Construction divisions lead an effort to promptly share information, investigate the cause, and propose recurrence prevention measures. We strive to prevent recurrence by disseminating this information horizontally to all construction sites and group companies, as well as to our cooperating companies through cooperating company organizations such as the Safety Cooperation Association and the Ken-ei-kai.
Based on the results of analysis of accidents that have occurred, we are working to prevent falls through thorough use of fall arrest devices (safety harnesses), activities to raise awareness of hazards prior to starting work, holding meetings before external scaffolding assembly and disassembly, and checking temporary facility plans utilizing BIM. Furthermore, we work to ensure full visibility of working radius, rated load, and other such factors for heavy machinery while striving to eliminate work that exceeds the capacity of heavy machinery through re-education of operators and related workers to prevent the recurrence of such accidents.
In FY2026, we will continue working to achieve our goal of zero accidents and disasters throughout the entire construction period, with a focus on prevention of falls, prevention of accidents involving heavy machinery, prevention of accidents from flying or falling objects, the prevention of accidents from unsafe behavior and fostering an awareness of safety through safety callouts, and accident prevention measures for elderly and inexperienced workers and enhancement of employee and worker education.

Framework for Promoting Health Management

In accordance with Haseko Group’s Declaration of Health, we established the Haseko Group Health Management Promotion Committee in FY2018. The Committee is chaired by the President of Haseko Corporation, its members are the respective officers in charge of departments of Haseko Corporation, the respective presidents of Group companies, occupational physicians, labor unions, and its secretariat consists of the Personnel Dept., the Safety Management Dept., the Health Promotion Office of Haseko Well Center, and the health insurance society. The Committee makes decisions on company-wide policies, targets, plans and progress related to the maintenance and promotion of employees’ health and shares related information.

Health management strategy

Under the Haseko Group’s Declaration of Health, with the aim of becoming a Group where all employees can stay healthy both mentally and physically and where each and every one can work with more vitality, we formulated the Haseko Group Health Management Strategy Map visualizing the relationship between the management issues to be solved and the investments in health (health promotion measures) required.

Initiatives

Physical health

HASEKO CLINIC, an in-house medical office that serves as the health management and disease prevention center for Group employees, plays a pivotal role in our efforts for the early detection of diseases through medical checkups and outpatient treatment.
The CLINIC not only conducts periodic medical checkups on all employees but also holds health seminars (e.g., improvement of diabetes, smoking cessation) and gives advice for the prevention of lifestyle-related diseases, in an effort to enhance their health. Under the scheme for raising employees’ awareness of good health, certain employees are offered PET-CT scanning, while female employees are entitled to comprehensive women-only medical examinations.

Mental health

We have a structure in place to provide care to employees to maintain their mental health ranging from counseling to reinstatement assistance, including stress checks, as well as a structure to give support to employees in the event of the onset of mental illness.
Specific services available are: "self-care," which involves counselling and telephone consultation by a professional body outside the Group; "line care," which is a periodic training session held for managers to educate them and raise their awareness for the prevention of mental illnesses among their subordinates; and "reinstatement assistance program," in which a support team including an occupational physician and the personnel division provides employees with full support at the Company level to return to work.

Refreshing

The Haseko Group believes that it is important for employees to have opportunities to expand their horizons in terms of hobbies and personal networks and opportunities to refresh themselves, in order to maintain their physical and mental health. For this reason, we not only directly operate a recuperation facility but also introduce recuperation facilities and resort condominiums to employees and encourage employees to utilize them.
Furthermore, Haseko Club and Everyone's Event, which are open to employees of the Haseko Group, provide the employees with opportunities to refresh themselves through physical exercise and cultural activities.
